During our testing we found that rounds from 1.130 to 1.155 OAL function very well with this platform. We tested this barrel with multiple manufacturers’ loads from 115 to 147 grains. The reloader will enjoy the deeper chamber which will allow for custom loads based on his or her shooting style. Further information can be shared upon request.

The LeadStar Arms LSA-9 comes from a joint venture between two of South Carolina’s very own firearms manufacturers. The engineers at LeadStar Arms set out to produce one of the best Pistol Caliber Carbines from the ground up that incorporates many of the features that competitive shooters need. These features include a built-in feedramp as well as a fully functional last round bolt hold open (LRBHO) that is integrated in the lower. The LSA-9 also includes a slightly flared magazine well along with a strategically placed oversized magazine release that greatly reduces reload times.

Every shooter knows that the soul of the rifle lies within the fire control system, bolt and barrel. With that in mind, the LSA-9 was equipped with the latest generation UMTactical bolt that is fitted with a standard AR style extractor, the popular Hiperfire 24c fire control group and Stainless Steel barrel that has a modified chamber that can accommodate both factory and custom loads. The barrel is fitted with a properly tuned, 9mm compensator that was developed in conjunction with the LSA-9 to make the most effective use of the gas column produced by the blowback action to keep your sights on point between transitions. Once assembled, we petitioned the legendary Kurt Grimes of Cen Cal Cerakote to perfect a color pattern that was unique to the Palmetto State Armory Brand and we are very happy with the outcome.

In the future, these carbines will be offered in solid blue, red and black, and will also be available as build kits. A video of the LeadStar LSA-9 can be found above.

Lower Receiver:LeadStar Skeletonized LRBHO

Our Patent Pending lower receiver includes integrated feed ramp for reliable feeding including hollow points and integrated LRBHO (last round bolt hold open) for AR-15 bolt release functionality. LRBHO is easily removed with 3 screws for competition shooters. Huge magwell entry chamfer for way faster and easier magazine changes, no aftermarket funnel is needed because it is so large. The TracStar™ magwell with full traction design is designed for the operator to grip and maintain weapon control even in the most extreme conditions. It also features a tension device to maintain rigidity between upper and lower receivers as well as a rear detent spring capture device to facilitate easier removal of the buffer tube. Built in trigger guard eliminates the need for a flip down trigger guard. Fully CNC machined from 7075-T6 aluminum for extreme precision and enhanced durability and skeletonized for further weight reduction.

Designed strictly with the competition shooter in mind, these barrels are capable of showing what the highest standards in barrel accuracy and quality truly are.

Handguard:LeadStar Grunt Free Float Handguard System

15" Ultra lightweight slim profile designed for both competition and duty use. CNC machined 6061-T6 aluminum. The unique design offers ultra-capture around the barrel nut, eliminating the requirement for anti-rotation tabs. It eliminates harmonics from attached accessories, greatly improving weapon accuracy. Full length picatinny CNC engraved numbered rail at the 12 o'clock position. Three M-LOK slots at the 3 o’clock and 9 o'clock positions and full length M-LOK slot sections at the 6 o'clock position for mounting additional rail sections or accessories.

Fire Control Group:Hiperfire 24c Fire Control Group

The HIPERTOUCH® 24C is the competition version of high precision fire-control drop-ins for installation in AR-15® and AR-10® type rifles. The HIPERTOUCH® name is short for High Performance TOUCH, 24 for user adjustable trigger weights and C for competition marksmen like 3-Gunners. It installs and functions just like the HIPERTOUCH® 24 but with half the pre-travel and a faster reset. Please note that HIPERTOUCH® FCGs may not work in lowers with pivot holes that are outside the MIL-Spec dimensions shown in RED.

Charging Handle:Geissele Airborne Charging Handle

The Airborne Charging Handle (ACH) was developed at the request of an elite organization famous for its expertise in aerial insertion. The organization requested a lower profile lever design to reduce the chances of snagging. The ACH’s lower profile design is especially ideal for rifles where the primary sighting system is a red dot or similar low profile optic system. The ambidextrous ACH is 3D machined from a solid block of aircraft grade 7075-T6 aluminum. Shortened levers are dual contoured with gently concaved radius cuts in the vertical and horizontal planes. The handling surfaces of the levers are checkered for confident operation while wearing gloves. A taller fence at the rear of the ACH aids in redirecting gas blow back when shooting with short barreled and suppressed weapon systems.

Buffer/Recoil Spring:Armaspec Stealth Recoil Spring

The Stealth Recoil Spring™ SRS™ is a self-contained multi-stage drop-in replacement for your standard buffer and spring. The Stealth Recoil Spring™ is designed to reduce felt recoil as well as keep the buffer spring from rubbing against the inner wall of the buffer tube. The buffer mass is designed to stay under constant tension against the bolt carrier and the O-ring on the head of the buffer mass prevents metal on metal contact. The polymer bumper goes towards the rear of the firearm and the weight mass with the O-ring goes towards the bolt carrier. This recoil spring system weighs just less than 6.0 ounces.
